<p>PROBLEM TO BE SOLVED: To operate a cancel lever easily by rotatably supporting a passive lever to an active lever and engaging and disengaging an engaging pin installed to the passive lever with and from the cancel lever on the center of rotation of the active lever. SOLUTION: A passive lever 34 is supported rotatably to an active lever 33, and an engaging pin 34c mounted on the passive lever 34 is engaged and disengaged with and from a cancel lever 35 on the center of rotation of the active lever 33 for controlling or permitting relative rotation to the passive lever 34. Consequently, the engaging pin 34c is placed on the center of rotation of the active lever 33 at all times at the time of closing operation and is not moved, and the lever ratio of the cancel lever 35 can be kept constant all the time. Accordingly, the operation of the cancel lever is not weighted by the operation timing, and excellent operability can be obtained.</p> |
